Embodiment Construction

[0015] see Figure 1-Figure 3 Explain, a kind of double-probe four-laser beam focus positioning device, it comprises positioning plate 7, No. 1 laser head 1 and No. 2 laser head 2;

[0016] No. 1 laser head 1 and No. 2 laser head 2 have two laser rays respectively, the two laser rays of No. 1 laser head 1 have a fixed focus, and the two laser rays of No. 2 laser head 2 have a fixed focus. The positioning plate 7 is processed with the first laser through hole 8, the second laser through hole 9, the third laser through hole 10 and the fourth laser through hole 11 arranged obliquely; the two laser rays of the first laser head 1 respectively pass through a No. 8 laser through hole 8 and No. 2 laser through hole 9. The two laser rays of No. 2 laser head 2 pass through No. 3 laser through hole 10 and No. 4 laser through hole 11 respectively. The plane of the laser head 2 is coplanar with the plane where the two laser rays of the second laser head 2 are located, and the fixed focus ...

Abstract

A double-probe four-laser-beam focus positioning device relates to= measurement and positioning devices. The focus positioning device comprises a positioning plate, a first laser head and a second laser head; the first laser head and the second laser head are provided with two laser rays respectively, and a first laser through hole, a second laser through hole, a third laser through hole and a fourth laser through hole which are obliquely formed are machined in the positioning plate, the plane where the two laser rays of the first laser head are located and the plane where the two laser rays of the second laser head are located are coplanar, and the fixed focuses of the two laser rays of the first laser head and the fixed focuses of the two laser rays of the second laser head coincide to form a four-laser-beam measuring focus. The first laser head and the second laser head are arranged in the same side of the positioning plate, and the four-laser-beam measuring focus is arranged in theother side of the positioning plate. The device is simple in structure and can determine the position of the laser focus.

Description

technical field [0001] The invention relates to a measurement and positioning device, in particular to a focus positioning device with two probes and four laser beams. Background technique [0002] At present, in the actual use of the dual-probe four-laser beam measuring equipment, the spatial relative position of the laser focus cannot be determined, which causes a lot of troubles in actual use. Contents of the invention [0003] The present invention aims to overcome the deficiencies of the prior art and provide a focus positioning device with two probes and four laser beams with simple structure and reliable positioning. [0004] Technical scheme of the present invention is: [0005] A double-probe four-laser beam focus positioning device, which includes a positioning plate, a No. 1 laser head and a No. 2 laser head; the No. 1 laser head and the No. 2 laser head have two laser rays respectively, and the two laser beams of the No. 1 laser head The ray has a fixed focus...
